DDA124EUQ-13-F

Overview

The DDA124EUQ-13-F is a PNP pre-biased dual transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and built-in biasing resistors (R1=22kΩ, R2=22kΩ) within a SOT363 package. The device is AEC-Q101 qualified for automotive applications and operates with a supply voltage up to -50V and continuous collector current of -100mA. Power dissipation is rated at 200mW, with a junction-to-ambient thermal resistance of 625°C/W. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Built-in biasing resistors simplify circuit design
• AEC-Q101 qualified for automotive reliability
• Totally lead-free and fully RoHS compliant

Applications

• Automotive switching circuits requiring specific change control
• General-purpose digital switching applications
• Driver circuits for low-power loads

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation before procurement. Confirm that the 'Q' designation aligns with your project's automotive qualification requirements. Ensure the reel size and tape width match your automated assembly equipment specifications. Cross-reference the date code key to confirm production timelines.

Selection Notes

Select this component when a dual PNP configuration with integrated base resistors is required in a compact surface-mount footprint. Verify that the 22kΩ resistor values suit your input drive levels. Consider the complementary NPN type if mixed polarity logic is needed. Check the maximum power dissipation limits against your thermal management strategy.

Part Context

This part belongs to the DDA series of pre-biased transistors designed for high-density PCB layouts. It shares the SOT363 package form factor with other variants in the family, allowing for standardized footprints across different resistor configurations. The 'UQ' suffix indicates automotive-grade qualification and specific packaging.

Replacement Considerations

Direct substitutes include other DDA124EU variants with identical electrical characteristics but potentially different packaging quantities. Complementary NPN equivalents are available in the DDC series. Verify pinout compatibility and thermal performance when replacing with non-OEM components.
